Two Headed Sharks was Found in Australia which is the Amazing Creation of Allah.
This two headed blue sharks can sound like a figment of the big screen, but they exist—and more are turning up worldwide.
A few years ago off Florida, fishermen hauled in a bull shark whose uterus contained a two-headed fetus. In 2008, another fisherman discovered a two headed blue shark embryo in the Indian Ocean.
And a 2011 study described conjoined twins discovered in blue sharks caught in the Gulf of California and northwestern Mexico. Two headed Blue sharks have produced the most recorded two-headed embryos because they carry so many babies—up to 50 at at time, says study leader Felipe Galván-Magaña, of the National Polytechnic Institute in Mexico.
Now, Spanish researchers have identified an embryo of an Atlantic sawtail catshark with two heads, according to a new study in the Journal of Fish Biology. While raising sharks for human-health research in the laboratory, a team noticed the unusual embryo in a see-through shark egg.
The catshark embyro was not your average two-headed beast—it’s the first such specimen known from an oviparous shark species, or a shark that lays eggs.
Researchers opened the egg to study the specimen, and study leader Valentín Sans-Coma says it’s unknown whether the deformed animal would have survived. Because it’s the first such conjoined twin found in egg-laying sharks, its likely that such offspring don’t live long enough for people to find them.
